With this update, we have also added support for the ‘orafce’ extension to emulate a subset of common functions and packages in version 9.6.6; and the ‘prefix’ extension to provide prefix range functions capability in version 9.6.6 .

To use the new versions, you can create a new Amazon RDS for PostgreSQL database instance with just a few clicks in the AWS Management Console, or upgrade an existing instance using point-and-click upgrades. An upgrade operation involves a short period of unavailability for your database instance. Learn more about upgrading your database instances from the Amazon RDS User Guide.

Amazon RDS for PostgreSQL makes it easy to set up, operate, and scale PostgreSQL deployments in the cloud. See Amazon RDS for PostgreSQL Pricing for regional availability.
